In this Aug. 25 photo, Republican presidential candidate Mitt Romney speaks as vice presidential running mate Rep. Paul Ryan, R-Wis., listens during a campaign rally in Powell, Ohio. According to Reich, Romney's campaign continues to claim that President Obama removed the work requirement from welfare, even though a dozen fact-checking organizations and websites say it isn't true.

A half dozen fact-checking organizations and websites have refuted Romney’s claims that Obama removed the work requirement from the welfare law and will cut Medicare benefits by $216 billion.

Last Sunday’s New York Times even reported on its front page that Romney has been “falsely charging” President Obama with removing the work requirement. Those are strong words from the venerable Times. Yet Romney is still making the false charge. Ads containing it continue to be aired.

Presumably the Romney campaign continues its false claims because they’re effective. But this raises a more basic question: How can they remain effective when they’ve been so overwhelmingly discredited by the media?

The answer is the Republican Party has developed three means of bypassing the mainstream media and its fact-checkers.

The first is by repeating big lies so often in TV spots – financed by a mountain of campaign money – that the public can no longer recall (if it ever knew) that the mainstream media and its fact-checkers have found them to be lies.

Together, these three mechanisms are creating a parallel Republican universe of Orwellian dimension – where anything can be asserted, where pollsters and political advisers are free to create whatever concoction of lies will help elect their candidate, and where “fact-checkers” are as irrelevant and intrusive as is the truth.

Democracy cannot thrive in such a place. To the contrary, history teaches that this is where demagogues take root. The Romney campaign has decided it won’t be dictated by fact-checkers. But a society without trusted arbiters of what is true and what is false is vulnerable to every lie imaginable.
